[NEW YORK] Wall Street was trading higher on Tuesday, helped by financial stocks, as investors await the Federal Reserve's decision on interest rates.
The central bank's two-day meeting will conclude with Fed Chair Janet Yellen's press conference at 2:00 pm ET on Wednesday.
The doves in the Fed are most likely to rule over the hawks who support higher rates in the near term, but investors will assess the comments for clues on a likely hike in December.
Investors are also watching the Bank of Japan's meeting which starts on Tuesday. Investors have little clue of what path the central bank could take to achieve its 2 per cent inflation target.
The markets have oscillated since Sept 9 as investors second-guess the Fed's intention following a series of contradicting comments on the timing of the next hike from its officials.
Traders have priced in a 15 per cent chance of a rate hike by Wednesday, according to the CME Group's FedWatch tool.
